woooEN PIPE.

SPECIFICATION forming part of Letters Patent No. 359,590, dated March22, 1887.

Application filed April 22, 188 Renewed February 10, 1887. Serial No.227,180. (No model.)

To all whom it-may concern.-

Be it known that I, CHARLES P. ALLEN, a citizen of the United States,residing at Denver, in the county of Arapahoe and State of Colorado,have invented certain new and useful Improvements in Wooden Pipes; and Ido hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to hooped pipes made of wooden staves.

My improvement consists, first, in interlocking the staves at thecrossjoints by a metallic tongue, and, secondly, of a metallic hoopcomposed of an approximately circular strapbolt and a coupling-shoe socombined that the hoops can be tightened around the pipe after it hasbeen placed around the same.

In the annexed drawings, Figure 1 represents a side elevation of aportion ofniy improved wooden pipe. Fig. 2- represents a cross sectionthereof. Fig. 3 represents aside elevation of a wooden pipe in which theslaves are arranged to break joints. Fig. aillustrates the coupling-shoein section and the ends of the strap-bolt in elevation. Fig. 5represents a plan of the coiiplingshoc. Fig. 6 illustrates astave end,showing the metallic tongue seated in the groove of the same. Figs. 4 to6 are drawn to a larger scale than Figs. 1 to 3.

The same letters of reference indicate identical parts in all thefigures.

A groove, a, is cut in each cnd'of each stave A deep enough to permitthe entrance of a metallic tongue, B, about half way, as shown in Fig.6. The length of the metallic tongue is a little in excess of the widthof the stave, so that the ends of the tongue may project a little fromeach side of the stave to enter the edges of the adjoining staves, asshown in Fig. 2, when two abutting stave ends are driven up.

The concealed metallic tongue will then interlock the abutting staveends with the adjoining staves, and thus form an excellent crossjoint.The hoops are composed of an approximately circular strap-bolt, O, and acouplingshoe, D. The couplingshoe is engaged from opposite ends by therespective ends of the strap-bolt. To this end the coupling-shoe isconstructed with a socket for the T-headed end of the strap-bolt, andwith a reverse socket for the nutted end of the strap-b0lt, theconstruction of these sockets and the length of the strap-bolt beingsuch, as shown in Fig. 4., that the end of the strap-bolt carrying thenut will overlap and hold in place the T-headed end thereof. The notaffords the means for tightening the strap-bolt around the pipe to thenecessary degree.

I claim as my invention 1. A hooped. pipe made of wooden staves whichare interlocked at each cross-joint by a concealed metallic tongueseated in grooves in the abutting stave ends and projecting a littleat'eacli side thereof into the edges of the ad joining staves,substantially as before set forth. 2. A pipe made of wooden staveshooped by hoops composed each of an approximately circular strap-boltand a coupling-shoe which engages the head at one end of thestrap-boltand the nut at the other end thereof.

3. A hoop composed of an approximately circular strap-bolt and acoupling-shoe, the

strap-bolt having a head at one end and a nut at the other end forengaging the couplingshoe from opposite ends, substantially as beforeset forth.

In testimony whereof I affix my signature in presence of two witnesses.
